CVE-2025-7426 is a critical vulnerability affecting MINOVA Information Services GmbH's TTA product, specifically version 11.17.0. The vulnerability involves the exposure of sensitive authentication credentials for an FTP service through an unauthenticated access vector on debug port 1604. This flaw allows remote attackers to retrieve active FTP account credentials without any authentication, granting them unauthorized access to sensitive internal data and import structures managed by the FTP server. The FTP service is often integrated into automated business processes such as Electronic Data Interchange (EDI) or other data integration workflows, meaning exploitation could lead to unauthorized data extraction, manipulation, or abuse of business-critical information flows. Additional debug ports (1602, 1603, and 1636) also leak service architecture details and system activity logs, further aiding attackers in reconnaissance and potential lateral movement. The vulnerability is classified under CWE-200 (Exposure of Sensitive Information), CWE-312 (Cleartext Storage of Sensitive Information), and CWE-532 (Information Exposure Through Log Files), highlighting multiple facets of sensitive data exposure. The CVSS 4.0 base score is 9.3 (critical), reflecting the vulnerability's network accessibility (AV:N), low attack complexity (AC:L), no authentication required (AT:N), no user interaction (UI:N), and a high impact on confidentiality and availability. No known exploits are currently reported in the wild, but the severity and ease of exploitation make this a high-risk issue requiring immediate attention.

For European organizations using MINOVA TTA version 11.17.0, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive business data. Unauthorized access to FTP credentials can lead to data breaches involving internal documents, import structures, and potentially sensitive business transactions processed via automated workflows like EDI. This could result in financial losses, regulatory non-compliance (e.g., GDPR violations due to unauthorized data exposure), operational disruptions, and reputational damage. The exposure of system architecture and activity logs further increases the risk by enabling attackers to map the environment and plan advanced attacks. Given the critical nature of the vulnerability and the integration of the affected FTP service in business-critical processes, exploitation could also lead to data manipulation, impacting business decisions and supply chain integrity. The lack of required authentication and user interaction means attackers can exploit this remotely and stealthily, increasing the threat to European enterprises relying on this software.

1. Immediate isolation or firewalling of debug ports 1602, 1603, 1604, and 1636 to restrict external access only to trusted administrators or internal networks. 2. Disable debug ports entirely in production environments if not strictly necessary for troubleshooting. 3. Rotate all FTP credentials associated with the TTA service to invalidate any potentially compromised accounts. 4. Implement network segmentation to limit access to the FTP server and associated services, ensuring only authorized systems and users can connect. 5. Monitor network traffic and logs for unusual FTP access patterns or connections to debug ports. 6. Engage with MINOVA Information Services GmbH for patches or updates addressing this vulnerability; if unavailable, consider temporary compensating controls such as VPN access restrictions or jump hosts for administration. 7. Conduct a thorough audit of data integrity and access logs to detect any signs of manipulation or unauthorized data extraction. 8. Educate internal teams on the risks of exposed debug interfaces and enforce strict change management and access control policies around sensitive infrastructure components.
